A06 - Learning from Failure: Negative and Null Results in Microscopy

It is no secret that there is a strong bias in science against reporting negative results. While there is much to learn from success, the greatest discoveries often stem from failures. The communication of negative results and artifacts is critical for accelerating scientific progress, yet the current publishing environment rarely rewards such efforts. Whether its rejection by an editor or relegation to the back of the poster hall, scientists have been conditioned to avoid reporting what doesn't work. This symposium is designed as an open, honest, and judgement-free forum for presenting artifacts, mistakes, mishaps, and null results.

A07 - In Memoriam of David Joy: Scanning Electron and Ion Microscopy

This symposium will celebrate the memory of David Joy, who was a pioneer in Scanning Electron and Ion Microscopy and in Monte Carlo simulations of electron trajectories in solids. He made seminal contributions in the theory and measurement of secondary electrons to develop and improve the imaging capabilities of electron and ion microscopes. This also led to seminal contributions in electron metrology related to the semi-conductor industry and low voltage scanning electron microscopy. He was a pioneer in the development of electron channeling imaging in bulk specimens in the SEM, Scanning Transmission Electron Microscopy in the SEM and in the variable pressure scanning electron microscope. He also made several contributions in the field of quantitative x-ray microanalysis with an emphasis on a date base that he updated regularly. He also developed the routine SMART to measure the resolution of SEM images. His contributions are endless. He also wrote several papers and books to explain electron microscopy to the community. But above all of this, he was a real gentleman and a mentor to so many of us. This symposium will be an occasion to remember is seminal work and as well how great he has been for the community.

A09 - Analytical Scanning Probe Microscopy

Non-e-beam-based, submicron analytical microscopes have undergone astonishing developments. Within scanning probe microscopy (SPM), analytical methods have expanded from mechanical (elastic/dissipative, including controlled rate/temperature) and non-mechanical (van der Waals, electrical/electrostatic, magnetic, thermal) interactions sensed at the tip-sample interface — under optional control of the chemistry or conductivity of the tip and/or immersion environment — to sensing the absorption of IR laser pulses acoustically at the tip or via near-field scattered IR light. Related methods include interferometric optical sensing of IR-excited acoustic pulses and tip-enhanced or confocal Raman microscopy. This symposium seeks to report new findings and foster the cross-discussion of methods.

P02 - Atomically Precise Manipulation of Materials

Atomically precise manipulation was first achieved with scanning probe microscopies, which continue to produce important advances using surface atoms and vacancies. However, recent developments in scanning transmission electron microscopy (STEM) instrumentation have made it possible to focus electron beams with sub-atomic precision, opening up new possibilities for manipulating strongly bound materials, including in the bulk. At the same time, other charged particle beams, including helium ion microscopy, have been added to the scientific arsenal, and advances in atomistic modeling and theory have elucidated new details of the beam-matter interaction, helping guide experiments. These breakthroughs have led to a series of studies on the controlled structuring, etching, deposition, phase change, and ultimately manipulation of individual atoms. This symposium will gather leading experts from this new frontier of materials science, including advances in machine learning and artificial intelligence, with a focus on atomic-level control.

P03 - Theory and Applications of Advanced Electron Tomography

Transmission electron microscopy (TEM) and scanning TEM (STEM) reveal the structure of materials across the nano-scale with achievable resolutions below one Ångstrom. However, these are only two-dimensional (2D) projections of complex three-dimensional (3D) structures. 3D morphology and composition are critical to determine the function of nano-structures used across many fields—such as energy, catalysis, electronics, and quantum materials. The success of electron tomography has fueled rapid innovation in quantitative, sub-nanoscale 3D analysis in electron microscopy that include recent achievements of atomic resolution and methods to determine 3D structure from few (even a single) projection image.

P04 - Correlative Microscopy of Rapidly Solidified Microstructures in Additive Manufactured Builds

Metals, ceramics, concrete, and polymers are being used in diverse additive manufacturing (AM) applications. Parts and components processed through these incremental layer-by-layer manufacturing techniques have microstructures that depend on a variety of factors like directed power source (e.g. laser or electron beam, arc-discharge), processing parameters (dwell, shape/contour region), choice of feedstock materials and post fabrication treatments. With modeling guided experimental control, site specific material properties can be engineered in AM parts because control of microstructure in pre-defined areas can be achieved. Contributions are invited on research of microstructures in additively manufactured components at multiple length scales through multi-modal microscopy/microanalysis characterization techniques, including OM, FESEM/EBSD/EDS/TKD, AEM, STEM, EELS, APT, EPMA and XCT. Correlation of microstructures to process conditions and final component properties are encouraged.

P05 - Microscopy and Microanalysis of Materials under Multiple Environmental Extremes

Future energy systems will expose materials to multiple extreme environments, often simultaneously, such as high temperatures, stress/strain, radiation, and corrosion/oxidation. When applied concurrently, these synergistic interactions can lead to unique material responses not found from sequential application of the same conditions. Understanding the mechanisms of materials' responses to multiple extremes therefore requires advanced characterization/testing, including in-situ analyses of separate and combined stimuli. This symposium will bring together experts in radiation effects, corrosion, mechanical behavior, and advanced microscopy, with an emphasis on the application of latest-generation methods of microscopy, microanalysis, and data analytics to tackle problems in materials under coupled extremes.

P07 - Prof. Wilbur C Bigelow Centenary Symposium In Situ Heating and Gas-Reaction Studies in Materials Sciences

This symposium will recognize and honor the distinguished career of University of Michigan Emeritus Prof. Wilbur C. Bigelow, MAS "Legend" and MSA Fellow, who turns 100 years old early in 2023. We invite submissions from former students and collaborators, as well as researchers working broadly in the area of in situ heating and gas reaction studies, topics of his interest over the past 15 years. Bigelow joined EMSA in 1950 and served in many roles including President in 1969, when the annual meeting was also held in Minneapolis. He taught his electron microscopy course for 35 years at Michigan. The techniques of in situ heating and gas reactions have evolved considerably from the mid 1960s when Bigelow studied the oxidation of Cu single crystal films using a JEOL JEM-6A with a 16-mm cine film camera. In retirement, Bigelow became active in designing specialized equipment for microscopy, and he collaborated into his 90s in pioneering the development of closed-cell gas-reaction techniques that are currently popular in the field. This symposium will feature talks and posters in the general areas of in situ heating and gas reactions (utilizing both closed-cell specimen holders and differentially pumped E-TEM techniques), all for materials science applications.
